FERMI 2 UFSAR 14.1-1 REV 19 10/14 CHAPTER 14:
INITIAL TESTS AND OPERATION This chapter describes the initial testing and operating program conducted at Fermi 2. The program describes the manner in which the testing and initial operation was performed, controlled, and documented for the following four testing and initial operating phases:
- a.
Construction Test Phase - the period during which the Construction Manager had responsibility for activities. Construction tests were generally carried out before the energization of equipment. The transfer of jurisdiction over equipment and systems from the Construction Manager to the System Completion Organization (SCO) occurred at the end of this period
- b.
Checkout and Initial Operations Test Phase - the period during which the Edison Startup Group conducted checkout and initial operations (CAIO) tests, including initial equipment energizing, flushing and cleaning operations, initial calibration of instrumentation, electrical wiring and equipment tests, valve testing, and initial equipment and system operation. Hydrotesting (a construction test) was also conducted during this phase
- c.
Preoperational Test Phase - the period during which approved preoperational tests were performed. The preoperational testing was the responsibility of the Edison Startup Group
- d.
Startup Test Phase - the period beginning with preparation for fuel loading and extending through 100 percent power and warranty demonstrations, where the Edison Startup Test Phase Group has responsibility for startup testing. A detailed description of this test phase is provided in Subsection 14.1.3. The startup test phase is subdivided into four parts:
- 1.
Fuel-loading and open-vessel tests
- 2.
Initial heating to rated temperature and pressure
- 3.
Power testing from rated temperature and pressure to 100 percent of rated output
- 4.
Warranty demonstration.
The test program also encompassed cold functional testing, the Surveillance Testing Program, and hot functional testing.
The construction, CAIO, and preoperation test phases were not necessarily performed in series. Certain test activities were conducted in parallel, such as construction tests with CAIO tests and CAIO tests with preoperational tests. On ASME Code systems, the contractor maintained the responsibilities of the Installer through the ASME Code hydrotesting and N-stamping. Overall systems jurisdiction, however, was maintained by Edison's SCO in these situations. Figure 14.1-1 is an overall test program outline.
This test program closely adhered to Regulatory Guide 1.68 (11/73), "Preoperational and Initial Startup Test Programs for Water-Cooled Power Reactors," while recognizing the specific requirements of the construction codes (ASME Section III).
FERMI 2 UFSAR 14.1-2 REV 19 10/14 14.1 TEST PROGRAM A comprehensive testing program was implemented at Fermi 2. This program was designed to ensure the following:
- a.
That the equipment and systems perform in accordance with General Design Criteria
- b.
That the plant is properly designed and constructed and is ready to operate in a manner that will not endanger the health or safety of the public
- c.
That the initial fuel loading is accomplished in a safe and efficient manner
- d.
That required verification of nuclear parameters is obtained
- e.
That the procedures for operating the plant are evaluated and demonstrated
- f.
That the operating staff is knowledgeable about the plant and procedures and fully prepared to operate the facility in a safe manner
- g.
That the plant achieves rated capacity while meeting all safety and environmental conditions.
Systems and components were tested and evaluated according to written and approved test procedures. An analysis of test results verified that each system or component performed satisfactorily. The written procedures for the initial tests and operation included objectives and prerequisites of the tests, initial conditions, precautions, the test method, acceptance criteria, return to normal status, and appropriate references.
During the preoperational and startup test phases, the permanent plant operating procedures, as described in Section 13.5, were used to support the preoperational and startup tests. The use of the plant system operating procedures in this manner enabled them to be verified and changed as necessary to become a safe, comprehensive set of system operating procedures.
14.1.1 Administrative Procedures (Testing)
The preoperational test program has been essentially completed for Fermi 2. All that presently (December 1988) remains is a small amount of testing to close out certain test items still open from previous testing on other systems.
The preoperational tests of the solid radwaste system were suspended in December 1987 because the system was unable to meet the design throughput values for ion-exchange resin waste streams. The objectives and test descriptions discussed in Subsection 14.1.3.2.17, as they apply to this system, will remain in effect should testing be resumed in the future.
The responsibilities and administrative controls necessary to complete this testing are defined in plant administrative procedures.

14.1.4 Fuel Load and Initial Operation - Startup Test Phase At the time of fuel loading, the preoperational test results for all completed tests were approved by the TRC, and access control was established, and the startup test phase began.
The startup test phase begins with preparation for fuel loading and extends to the completion of the warranty demonstration. This phase is subdivided into the following four parts:
- a.
Fuel loading and open vessel tests
- b.
Initial heatup
- c.
Power tests
- d.
Warranty demonstration.
This section describes each of the parts of the startup test phase, the tests to be conducted and their sequence, the administrative methods to be used for procedure and test control, and the functions of the Edison Startup Test Phase Group. Normal plant personnel responsibilities, authorities, and qualifications are given in Chapter 13. The startup test phase and all associated testing activities adhere closely to Regulatory Guide 1.68, "Preoperational and Initial Startup Test Programs for Water-Cooled Power Reactors."
The overall objectives of the startup test phase are as follows:
- a.
To achieve an orderly and safe initial core loading
- b.
To perform all testing and measurements necessary to determine that the approach to initial criticality and the subsequent power ascension are accomplished safely and orderly
- c.
To conduct low-power physics tests sufficient to ensure that physics design parameters have been met
- d.
To conduct initial heatup and hot functional testing so that hot integrated operation of all systems is shown to meet design specifications
- e.
To conduct an orderly and safe power ascension program, with requisite physics and systems testing, to ensure that the plant operating at power meets design intent
FERMI 2 UFSAR 14.1-54 REV 19 10/14
- f.
To conduct a successful warranty demonstration program.
Tests conducted during the startup test phase consist of major plant transients, stability tests, and a remainder of tests that are directed toward demonstrating correct performance of the nuclear boiler and numerous auxiliary plant systems while at power. Certain tests may be identified with more than one part of the startup test phase. Table 14.1-1 shows a general view of the startup test phase program and should be considered in conjunction with Figure 14.1-2, which shows, graphically, the various test areas as a function of core thermal power and flow.
14.1.4.1 Fuel Loading and Open Vessel Tests Fuel loading began when the preoperational testing program described in Subsection l4.l.3 had been completed to the maximum extent practical and when the TRC and the augmented OSRO approved the initial fuel loading.
14.1.4.2 Initial Heatup The heatup testing phase has been completed at Fermi 2. All required tests were completed successfully. A more detailed discussion of the testing performed during this period is given in the test abstracts (Subsection 14.1.4.8), which were applicable for this phase of testing.
14.1.4.3 Power Tests Many of the tests of the power test phase are repeated several times at different test levels.
Table 14.1-1 and Figure 14.1-2 show, in general, the planned order of execution for the full series of tests.
Coolant chemistry tests and radiation surveys are made at each principal test level to preserve a safe and efficient power increase. The effect of control rod movement on other parameters (e.g., electrical output, steam flow, and neutron flux level), is examined for different power conditions. Following the first reasonably accurate heat balance, the APRMs and IRMs are readjusted if necessary.
At major power levels, the LPRMs and APRMs are calibrated. Completion of the process computer checkout is made for all variables, and the various options are compared with independent calculations as soon as significant power levels are available. Further tests of the RCIC and the HPCI systems are made with and without injection into the RPV.
Collection of data from the system expansion tests is completed for those piping systems that had not previously reached full operating temperatures. The axial and radial power profiles are explored fully by means of the TIP system at representative power levels during power ascension.
Core performance evaluations are made at selected test points above the 10 percent power level; the work involves the determination of core thermal power, maximum linear heat generation rate, and minimum critical power ratio (MCPR).
Overall plant stability in relation to minor perturbations is shown by the following group of tests:
FERMI 2 UFSAR 14.1-55 REV 19 10/14
- a.
Pressure regulator setpoint change
- b.
Pressure regulator failure
- c.
Feedwater system setpoint change
- d.
Flow control setpoint change.
The category of major plant transients includes full closure of all the MSIVs, fast closure of turbine generator control/stop valves, loss of the main generator and offsite power, feedwater system heating loss, trip of a feedwater pump, and a recirculation pump trip. The plant transient behavior is recorded for each test, and the results are compared with the predicted design performance.
A test is made of the safety/relief valves (SRVs) in which leaktightness and general operability are demonstrated. At selected major power levels, the jet pump flow instrumentation is calibrated. The local control loop performance, based on the drive motor, fluid coupler, generator, drive pump, jet pumps, and control equipment, is checked.
Vibration testing is conducted at several power conditions as the operating power level is raised.
Heat load performance of certain fluid and ventilation systems is demonstrated. These systems were tested previously during the preoperational test phase to demonstrate their operability and their ability to meet safety criteria, but could not be tested for heat load performance until normal plant operating conditions were available. The demonstration of heat load performance includes tuning of system controls and base line data acquisition for future performance evaluation. These continuations of preoperational tests will be treated, for administrative control purposes, as separate tests conducted in parallel with the startup tests.
14.1.4.4 Warranty Demonstration The warranty test phase consists of a demonstration in which the steaming rate and steam quality are shown to comply with contractual obligations. This demonstration includes a 100-hr full-power run.
14.1.4.5 Startup Test Procedure Preparation, Approval, and Modification Startup Test Procedures are prepared by Edison or their designated agents. These procedures are based on GE-supplied Startup Test Specifications and other source documents. Draft startup test procedures are reviewed by the Edison Startup Test Phase Group, then submitted to the augmented OSRO for review and approval.
Minor modifications to the approved procedures can be made if the modification does not change the intent of the test. The responsible Startup Test Phase Engineer and an Edison Senior Reactor Operator (SRO) can provide approval of the minor modifications. Minor changes are handled administratively in a manner similar to normal plant procedures as described in Section 13.5.
Major modifications to the approved procedures are those that change the intent of the startup test or that will change safety margins already approved. Such proposed modifications must undergo review and approval of the augmented OSRO prior to test performance. Major
FERMI 2 UFSAR 14.1-56 REV 19 10/14 changes to procedures required after the start of testing necessitate a halt of the test until the augmented OSRO reviews and approves the proposed major modifications. If Startup Test Specification Level 1 Criteria are involved in the major change, the GE Site Operations Manager may be required to obtain approval of the intended change from GE Engineering.
14.1.4.6 Startup Test Execution Startup test performance and supervision is the responsibility of the Startup Test Phase Engineer and plant personnel who obtain technical direction, where applicable, from the GE Operations Shift Engineers and Test Design and Analysis Shift Test Engineers. Startup Test Phase Engineers are assigned to follow startup tests on a shift basis.
All startup tests are performed according to approved startup test procedures.
14.1.4.7 Startup Test Results Approval and Approvals for Power Escalation All startup tests are documented by the responsible Startup Test Phase Engineer. The test report is reviewed by the Startup Engineer - Test phase or his delegate before submittal to the augmented OSRO and Plant Manager for approval.
During startup testing, many of the tests are repeated several times at different test levels or test conditions. These test conditions are used for convenience to define the basic plant conditions of core power and core flow.
The sequence in which each test condition must be performed is shown below. An exception to this sequence is Test Condition 4, which may be conducted any time after the completion of Test Condition 3.
Individual tests within each test condition may be performed in any desired sequence.
However, all testing within each test condition must be completed before proceeding to the next test condition except for justifiable exceptions approved by the augmented OSRO and Plant Manager.
Most of the test conditions are shown in terms of reactor power versus core flow on Figure 14.1-2. The test condition designations and sequence are further defined as follows:
Test Conditions
- a.
Pre fuel-load tests, fuel-load tests, and open vessel tests
- b.
Heatup testing
- c.
Test Condition 1
- d.
Test Condition 2
- e.
Test Condition 3
- f.
Test Condition 4 (may be performed at any time following Test Condition 3)
- g.
Test Condition 5
- h.
Test Condition 6 and warranty run tests.
FERMI 2 UFSAR 14.1-57 REV 19 10/14 Prior to initiating each test condition, the augmented OSRO reviews the test results of the previous test condition. It determines that the results are adequate and present no safety hazards to personnel, equipment, or the general public, and that any test exceptions have been properly dispositioned. The augmented OSRO presents its findings and recommendations to the Plant Manager. The Plant Manager, when satisfied that the test results are proper and that the conditions required for the next test condition of startup testing are available, will give approval to advance in the testing sequence.
14.1.4.8 General Discussion of Startup Tests The startup test program is specified on the following pages. The general sequence planned can be obtained from Table 14.1-1. Start at the left side of the page and move to the right.
The sequence of tests in a column is as follows:
- a.
Core performance analysis
- b.
Steady-state testing
- c.
Control system tuning
- d.
Major transients.
In describing the objectives of a test, an attempt is made to identify those operating and safety-oriented characteristics of the plant which are being explored.
Where applicable, a definition of the relevant acceptance criteria for the test is given and is designated either Level l or Level 2. A Level 1 criterion normally relates to the value of a process variable assigned in the design of the plant, component systems, or associated equipment. If a Level 1 criterion is not satisfied, the plant will be placed in a suitable hold-condition until resolution is obtained. Tests compatible with this hold-condition may be continued. Following resolution, applicable tests must be repeated to verify that the requirements of the Level 1 criterion are now satisfied.
A Level 2 criterion is associated with expectations relating to the performance of systems. If a Level 2 criterion is not satisfied, operating and testing plans would not necessarily be altered. The measurements and analytical techniques used for the predictions would be investigated.
Acceptance criteria values presented in the following test descriptions will be verified against the approved Technical Specifications prior to Startup Test Procedure performance. Where differences exist, the Technical Specifications shall take precedence.
A detailed and specific startup test procedure is written for each of the startup tests. The startup test procedure is the document which provides detailed instruction for each test when performed by the test personnel. A list of the startup tests presently planned, together with subsection sequence for use in locating a particular test discussion, follows.

Specific objectives of the test program include evaluation of fuel performance, evaluations of filter-demineralizer operations by direct and indirect methods, confirmation of condenser integrity, demonstration of proper steam separator-dryer operation, measurement and calibration of the offgas system, and calibration of certain process instrumentation. Data for these purposes are secured from a variety of sources: plant operating records, regular routine coolant analysis, radiochemical measurements of specific nuclides, and special chemical tests.
Description Prior to fuel loading, a complete set of chemical and radiochemical samples is taken to ensure that all sample stations are functioning properly, and to determine initial concentrations. Subsequent to fuel loading, during reactor heatup and at each major power level change, samples are taken and analyzed to determine the chemical and radiochemical quality of primary coolant, the amount of radiolytic gas in the steam, gaseous activities leaving the air ejectors, decay times in the offgas lines, and performance of filter-demineralizers. Calibrations are made on monitors in the stack, liquid waste system, and liquid process lines.
Criteria Level 1 Chemical factors defined in the Technical Specifications and Fuel Warranty must be maintained within the limits specified. The activity of gaseous and liquid effluents must
FERMI 2 UFSAR 14.1-60 REV 19 10/14 conform to license limitations. Water quality must be known at all times and remain within the guidelines of the Water Quality Specifications.
Level 2 Not applicable.
14.1.4.8.2 Radiation Measurements Purpose The purposes of this test are to determine the background radiation levels in the plant environs prior to operation for base data on activity buildup, and to monitor radiation at selected power levels to ensure the protection of personnel during plant operation.
Description A survey of natural background radiation throughout the plant site is made prior to fuel loading. Subsequent to fuel loading, during reactor heatup and at major levels during the initial power ascension program, gamma radiation level measurements, and, where appropriate, thermal and fast neutron dose-rate measurements, are made at significant locations throughout the plant. All potentially high radiation areas are surveyed.
Criteria Level 1 The radiation doses of plant origin and the occupancy times of personnel in radiation zones shall be controlled consistent with the guidelines of the standards for protection against radiation outlined in 10 CFR 20, "Standards for Protection Against Radiation," and NRC General Design Criteria.
Level 2 Not applicable.
14.1.4.8.3 Fuel Loading Purpose The purpose of this test is to load fuel safely and efficiently to the full core size.
Description Prior to fuel loading, control rods and neutron sources and detectors are installed and tested.
Fuel loading begins at the center of the core and proceeds radially to the fully loaded configuration. Control rod functional tests, subcriticality checks, and shutdown margin demonstrations are performed periodically during the loading.
Criteria Level 1 The partially loaded core must be subcritical by at least 0.38 percent k/k with the analytically determined strongest rod fully withdrawn.
FERMI 2 UFSAR 14.1-61 REV 19 10/14 Level 2 Not applicable.
14.1.4.8.4 Full Core Shutdown Margin Purpose The purpose of this test is to demonstrate that the reactor is subcritical throughout the first fuel cycle with any single control rod fully withdrawn.
Description This test is performed in the fully loaded core in the Xenon-free condition. The shutdown margin is measured by withdrawing the control rods until criticality is reached. If criticality is not reached with in-sequence control rods in the configuration corresponding to the required shutdown margin reactivity, the shutdown margin is satisfied. Additional in-sequence control rods are then withdrawn until the reactor is critical. The difference between the measured Keff and the calculated Keff for the in-sequence critical will be applied to the calculated shutdown margin to obtain the true shutdown margin.
Criteria Level 1 The shutdown margin of the fully loaded core with the analytically determined strongest rod withdrawn must be at least 0.38 percent k/k plus an additional margin for exposure.
Level 2 Criticality should occur within +/-1.0 percent k/k of the predicted critical.
14.1.4.8.5 Control Rod Drive System Purpose The purposes of the CRD system test are to demonstrate that the CRD system operates properly over the full range of primary coolant temperatures and pressures from ambient to operating, and to determine the initial operating characteristics of the entire CRD system.
Description The CRD tests performed during the open vessel, heatup, and power test parts of the startup test program are designed as an extension of the tests performed during the preoperational CRD system tests. Thus, after it is verified that all CRDs operate properly when installed, they are tested periodically during heatup to ensure that there is no significant binding caused by thermal expansion of the core components. A list of all CRD tests to be performed during startup testing is given in Table 14.1-2.
Criteria Level 1 Each CRD must have a normal withdrawal speed less than, or equal to, 3.6 in./sec, indicated by a full 12-ft stroke in greater than, or equal to, 40 sec. The mean scram time of all operable
FERMI 2 UFSAR 14.1-62 REV 19 10/14 CRDs with functioning accumulators must not exceed the following times (scram time is measured from the time the pilot scram valve solenoids are deenergized).
Position Inserted From Fully Withdrawn Scram Time (sec) 46 0.358 36 1.096 26 1.860 06 3.419 The mean scram time of the three fastest CRDs in a two-by-two array must not exceed the following times (scram time is measured from the time the pilot scram valve solenoids are deenergized):
Position Inserted From Fully Withdrawn Scram Time (sec) 46 0.379 36 1.161 26 1.971 06 3.624 Level 2 Each CRD must have a normal insertion or withdrawal speed of 3.0 +/- 0.6 in./sec, indicated by a full 12-ft stroke in 40 to 60 sec. With respect to the CRD friction tests, if the differential pressure variation exceeds 15 psid for a continuous drive-in, a settling test must be performed. In this case, the differential settling pressure should not be less than 30 psid, nor should it vary by more than 10 psid over a full stroke.
14.1.4.8.6 Source Range Monitor Performance and Control Rod Sequence Purpose The purpose of this test is to demonstrate that the operational sources, source range monitor (SRM) instrumentation, and rod withdrawal sequences provide adequate information to achieve criticality and increase power in a safe and efficient manner. The effect of typical rod movements on reactor power will be determined.
Description
FERMI 2 UFSAR 14.1-63 REV 19 10/14 The operational neutron sources will be installed and SRM count rate data will be taken during rod withdrawals to critical and compared with stated criteria on signal and signal count-to-noise count ratio. A withdrawal sequence has been calculated that completely specifies control rod withdrawals from the all-rods-in condition to the rated power configuration.
Movement of rods in a prescribed sequence is monitored by the rod worth minimizer (RWM) and rod sequence control system (RSCS), which will prevent out-of-sequence withdrawal.
Also, not more than two rods may be inserted out of sequence. As the withdrawal of each rod group is completed through Test Condition 1 (see Figure 14.1-2), the electrical power, steam flow, control valve position, and average power range monitor (APRM) response are recorded.
Criteria Level 1 There must be a neutron signal count-to-noise count ratio of at least 2:1 on the required operable SRMs or fuel-loading chambers. The minimum count rate, as defined by the Technical Specifications, must be met on the required operable SRMs or fuel-loading chambers.
Level 2 Not applicable.
14.1.4.8.7 Water Level Reference Leg Temperature Measurement Purpose The purpose of this test is to measure the reference leg temperature and recalibrate the instruments if the measured temperature is different from the value assumed during the initial calibration.
Description To monitor the reactor vessel water level, four level instrument systems are provided. These are the following:
- a.
Shutdown (floodup) range
- b.
Narrow range
- c.
Wide range
- d.
Fuel (core level) range.
These systems are used, respectively, as follows:
- a.
Water level measurement, cold shutdown conditions
- b.
Feedwater flow and water level control functions, hot operating conditions
- c.
Safety functions, hot operating conditions
- d.
Safety functions, postaccident conditions.
FERMI 2 UFSAR 14.1-64 REV 19 10/14 This test will be done at rated temperature and pressure and under steady-state conditions and will verify that the reference leg temperatures of the instruments are the values assumed during initial calibration. If not, the instruments will be recalibrated using the measured value.
Criteria Level 1 Not applicable.
Level 2 The difference between the actual reference leg temperature(s) and the value(s) assumed during initial calibration shall be less than that amount that will result in a scale endpoint error of 1 percent of the instrument span for each range.
14.1.4.8.8 Intermediate Range Monitor Performance Purpose The purpose of this test is to adjust the intermediate range monitor system (IRMS) to obtain an optimum overlap with the SRM and APRM systems.
Description Initially, the IRM system is set to maximum gain. After the APRM calibration, the IRM gains are adjusted to optimize the IRM overlap with the SRMs and APRMs.
Criteria Level 1 Each IRM channel must be on scale before the SRMs exceed their rod block setpoint. Each APRM must be on scale before the IRMs exceed their rod block setpoint.
Level 2 Not applicable.
14.1.4.8.9 Local Power Range Monitor Calibration Purpose The purpose of this test is to calibrate the LPRM system.
Description The LPRM channels are calibrated to make the LPRM readings proportional to the neutron flux in the LPRM water gap at the chamber elevation. Calibration factors are obtained through the use of either an off-line or a process computer calculation that relates the LPRM reading to average fuel assembly power at the chamber height.
Criteria Level 1 Not applicable.
FERMI 2 UFSAR 14.1-65 REV 19 10/14 Level 2 Each LPRM reading will be within 10 percent of its calculated value.
14.1.4.8.10 Average Power Range Monitor Calibration Purpose The purpose of this test is to calibrate the APRM system.
Description Generally a heat balance is made each shift and after each major power level change. Each APRM channel reading is adjusted to be consistent with the core thermal power as determined from the heat balance. During heatup, a preliminary calibration is made by adjusting the APRM amplifier gains so that the APRM readings agree with the results of a constant heatup rate heat balance. The APRMs will be recalibrated in the power range by a heat balance as soon as adequate feedwater indication is available.
Criteria Level 1 The APRM channels must be calibrated to read equal to, or greater than, the actual core thermal power. Technical Specification and fuel warranty limits on APRM scram and rod block shall not be exceeded. In the startup mode, all APRM channels must produce a scram at less than, or equal to, 15 percent of rated thermal power. Recalibration of the APRM system is not necessary from a safety standpoint if at least two APRM channels per RPS trip circuit have readings greater than, or equal to, core power.
Level 2 If the above criteria are satisfied, then the APRM channels will be considered to be reading accurately if they agree with the heat balance to within (+7, -0) percent of rated power.
14.1.4.8.11 Process Computer Purpose The purpose of this test is to verify the performance of the process computer under plant operating conditions.
Description Computer system program verifications and calculational program validations at static and at simulated dynamic input conditions are tested preoperationally at the computer supplier's site and following delivery to the plant site. Following fuel loading, during plant heatup, and the ascension to rated power, the nuclear steam supply system (NSSS) and the balance-of-plant (BOP) system process variables sensed by the computer as digital or analog signals will become available. Verify that the computer is receiving correct values of sensed process variables, and that the results of performance calculations of the NSSS programs are correct.
At steady-state power conditions the Dynamic System Test Case will be performed.

14.1.4.8.12 Reactor Core Isolation Cooling System Purpose
FERMI 2 UFSAR 14.1-67 REV 19 10/14 The purpose of this test is to verify the proper operation of the reactor core isolation cooling (RCIC) system over its expected operating pressure range.
Description The RCIC system test consists of two parts: injection to the CST and injection to the reactor vessel.
The CST injections consist of manual and automatic mode starts at 150 psig and near rated reactor pressure conditions. The pump discharge pressure during these tests is throttled to be 100 psi above reactor pressure. The initial testing is for demonstrating operability and making initial controller adjustments. This is followed by vessel injections beginning with cold RCIC hardware. Cold is defined as a minimum of 3 days without any kind of RCIC operation.
The vessel injections verify the adequacy of the startup transient and also include steady-state controller adjustments. Two consecutive vessel injections starting from cold conditions and with the same equipment settings are necessary to demonstrate system reliability.
After final controller settings are determined, CST injections are done with initially cold RCIC equipment. These runs provide a benchmark for future surveillance testing.
A demonstration of an extended operation of 30 minutes of continuous running or until the pump and turbine oil temperature is stabilized, is scheduled at a convenient time during the test program.
Criteria Level 1 The average pump discharge flow must be equal to, or greater than, 100 percent-rated value after 50 sec have elapsed from initiation on all auto start at any reactor pressure between 150 psig and rated. With pump discharge at any pressure between 250 psig and 100 psi above rated pressure, the required flow is 600 gpm. (The 100 psi is a conservatively high value for line losses. The measured value may be used if available.)
The RCIC turbine shall not trip or isolate during auto or manual starts. If any Level 1 criteria are not met, the reactor will be allowed to operate only up to a restricted power level defined in the Startup Test Procedure.
Level 2 The turbine gland seal condenser system shall be capable of preventing steam leakage to the atmosphere. The DP switch for the RCIC steam supply line high-flow isolation trip shall be adjusted to actuate at 300 percent of the maximum required steady-state flow, with the reactor assumed to be near the pressure for main relief valve actuation. For small speed or flow changes in either manual or automatic mode, the decay ratio of each recorded RCIC system variable must be less than 0.25.
To provide a margin on the overspeed trip and isolation, the first and subsequent speed peaks on the transient start shall not exceed the rated speed of the RCIC turbine by more than 5 percent.
FERMI 2 UFSAR 14.1-68 REV 19 10/14 14.1.4.8.13 High Pressure Coolant Injection System Purpose The purpose of this test is to verify the proper operation of the high pressure coolant injection (HPCI) system over its expected operating pressure range.
Description The HPCI system test consists of two parts: injection to the CST and injection to the reactor vessel.
The CST injections consist of manual and automatic starts at 150 psi and at rated reactor pressure. The pump discharge pressure during these tests is throttled to 100 psi above reactor pressure. The initial testing is for demonstrating operability and making initial controller adjustments. This is followed by vessel injections beginning with cold HPCI hardware.
Cold is defined as a minimum of 3 days without any kind of HPCI operations.
The vessel injections verify the adequacy of the startup transient and also include steady-state controller adjustments. Two consecutive vessel injections starting from cold conditions with the same equipment settings are necessary to demonstrate system reliability.
After final controller settings are determined, CST injections are done with initially cold HPCI equipment. These runs provide a benchmark for future surveillance testing.
A demonstration of an extended operation of 30 minutes of continuous running or until pump and turbine oil temperature is stabilized, is scheduled at a convenient time during the test program.
Criteria Level 1 The average pump discharge flow must be equal to, or greater than, the 100 percent-rated value with a system response time of less than or equal to 30 sec as defined in the Technical Specifications at any reactor pressure between 150 psig and rated. With pump discharge at any pressure between 250 psig and 100 psi above rated pressure, the flow should be at least 5000 gpm. (The 100 psi is a conservatively high value for line losses. The measured value may be used if available.) The HPCI turbine shall not trip or isolate during auto or manual starts.
Level 2 The turbine gland seal condenser system shall be capable of preventing steam leakage to the atmosphere. The delta P switch for the HPCI steam supply line high flow isolation trip shall be adjusted to actuate at 300 percent of the maximum required steady-state flow with reactor assumed to be near the pressure for main relief valve actuation. For small speed or flow changes in either manual or automatic mode, the decay ratio of each recorded HPCI system variable must be less than 0.25.
The margin to avoid the overspeed trip shall be at least 10 percent of the nominal overspeed trip setpoint of 5000 rpm during all auto starts of the HPCI system.
FERMI 2 UFSAR 14.1-69 REV 19 10/14 14.1.4.8.14 Selected Process Temperatures Purpose The purposes of this procedure are to establish the proper setting of the low speed limiter for the recirculation pumps to avoid coolant temperature stratification in the reactor pressure vessel (RPV) bottom head region, to provide assurance that the measured bottom head drain temperature corresponds to bottom head coolant temperature during normal operations, and to identify any reactor operating modes that cause temperature stratification.
Description During initial heatup while at hot-standby conditions, the bottom drain line temperature, recirculation loop suction temperature, and applicable reactor parameters are monitored as the recirculation pump flow is slowly lowered to minimum stable flow. The parameters above are recorded during pump trips as well. The effects of cleanup flow, CRD flow, and power level are investigated as operational limits allow. Utilizing these data, it can be determined if coolant temperature stratification occurs when the recirculation pumps are on and if so, what minimum pump speed will prevent it. A comparison of recirculation loop coolant temperature with bottom drain line temperature when core flow is 100 percent will be performed.
Criteria Level 1 The reactor recirculation pumps shall not be started nor flow increased unless the coolant temperatures between the steam dome and bottom head drain are within 145°F. The recirculation pump in an idle loop must not be started, active loop flow must not be raised, and power must not be increased unless the idle loop suction temperature is within 50°F of the active loop suction temperature. If two pumps are idle, the loop suction temperature must be within 50°F of the steam dome temperature before pump startup.
Level 2 During operation of two recirculation pumps at rated core flow, the bottom head temperature as measured by the bottom drain line thermocouple should be within 30°F of the recirculation loop temperatures.
14.1.4.8.15 System Expansion Purpose The purpose of this procedure is to verify that major piping of the NSSS and related auxiliary systems is free and unrestrained with regard to thermal expansion, and to verify that the thermal movement of the piping and associated support system components is consistent with the analytical predictions of the piping system stress analyses.
Description Observations and/or recordings of the thermal expansion movements of key points on the piping of the NSSS and related auxiliary systems are made as the piping systems are brought initially from ambient to operational temperature. The points ordinarily chosen to be
FERMI 2 UFSAR 14.1-70 REV 19 10/14 monitored will be those points in each piping system that are expected to exhibit relatively large thermal deflections and/or experience large thermally induced stresses, as predicted by the piping system stress analysis.
Pipe position will be recorded or logged at the ambient, intermediate, and maximum expected temperature points described above.
One or more of the following methods of monitoring piping system thermal movement will be employed, depending on practicality and accessibility limitations:
- a.
Actual observation of piping system thermal behavior by a member or delegate of the Edison Startup Group
- b.
Installation of local mechanical recording devices (scratch or dial gages)

Detailed discussion concerning thermal expansion testing is presented in Subsection 3.9.1.1.
Criteria Acceptance criteria for this test are presented in Subsection 3.9.1.1.5.

14.1.4.8.18 Steam Production (Deleted)
This subsection has been deleted because the test is performed only for warranty demonstration purposes unrelated to safety. The test will be conducted as a demonstration test.
14.1.4.8.19 (Not Applicable) 14.1.4.8.20 Pressure Regulator Purpose
- a.
To determine the optimum settings for the pressure control loop by analysis of the transients induced in the reactor pressure control system by means of the pressure regulators
FERMI 2 UFSAR 14.1-72 REV 19 10/14
- b.
To demonstrate the takeover capability of the backup pressure regulator on failure of the controlling pressure regulator and to set spacing between the setpoints at an appropriate value
- c.
To demonstrate smooth pressure control transition between the control valves and bypass valves when the reactor generates more steam than is used by the turbine.
Description The pressure setpoint is decreased rapidly and then increased rapidly by up to 10 lb/in.2, and the response of the system will be measured in each case. It is desirable to accomplish the setpoint change in less than 1 sec. At specified test conditions, the load limit setpoint is set so that the transient is handled by control valves, bypass valves, or both. The backup regulator is tested by simulating a failure of the operating pressure regulator so that the backup regulator takes over control. The response of the system is measured and evaluated and regulator settings are optimized. The matrix of test mode and conditions is tabulated below.
Test Condition Number Mode Input 1
2 3
5 6
CV Setpoint No Yes Yes Yes Yes CV Fail to back up No Yes Yes No Yes BPV Setpoint Yes Yes No Yes Yes BPV Fail to back up Yes Yes No No Yes Recirc. modes Manual Manual Manual Manual Manual Criteria Level 1 The decay ratio must be less than 1.0 for each process variable that exhibits oscillatory response to pressure regulator changes.
Level 2 In all tests the decay ratio must be less than or equal to 0.25 for each process variable that exhibits oscillatory response to pressure regulator changes when the plant is operating above the lower limit setting of the master flow controller.
Pressure control deadband, delay, etc., shall be small enough for steady-state limit cycles, if any, to produce turbine steam flow variations no larger than 0.5 percent of rated flow.
During the simulated failure of the controlling pressure regulator along the 100 percent rod line (Figure 14.1-2), if the setpoint of the backup pressure regulator is optimally set, the backup regulator shall control the transient so that the peak neutron flux or peak vessel pressure remains below the scram settings by 7.5 percent and 10 lb/in.2, respectively.
FERMI 2 UFSAR 14.1-73 REV 19 10/14 After a pressure setpoint adjustment, the time between the setpoint change and the occurrence of the pressure peak shall be 10 sec or less. (This applies to pressure setpoint changes made with the recirculation system in the master or local manual control mode.)
14.1.4.8.21 Feedwater System Purpose
- a.
To adjust the feedwater control system for acceptable reactor water level control
- b.
To demonstrate stable reactor response to subcooling changes
- c.
To demonstrate the capability of the automatic core flow runback feature to prevent low water level scram following the trip of one feedwater pump
- d.
To demonstrate adequate response to feedwater heating loss
- e.
To determine the maximum feedwater runout capability.
Description Reactor water level setpoint changes of approximately 3 to 6 in. will be used to evaluate and adjust the feedwater control system settings for all power and feedwater pump modes. The level setpoint changes will also demonstrate core stability to subcooling changes. One of two operating feedwater pumps will be tripped and the automatic flow runback circuit will act to drop power to within the capacity of the remaining pump. The worst single-failure case of feedwater temperature loss will be performed and the resulting transients recorded between 80 and 90 percent power and near full core flow rate. Data will be taken between 50 and 100 percent power to allow determination of the maximum feedwater runout capability.
Criteria Level 1 The response of any level-related variable to any test input change, or disturbance, must not diverge during the setpoint changes.
For the feedwater temperature loss test, the maximum feedwater temperature decrease due to a single-failure case must be less than or equal to 100°F. The resultant MCPR must be greater than the fuel thermal safety limit.
For the feedwater temperature loss test, the increase in simulated heat flux cannot exceed the predicted Level 2 value by more than 2 percent. The predicted value will be based on the actual test values of feedwater temperature change and power level.
The feedwater flow runout capability must not exceed the assumed value in the FSAR.
Level 2 Level control system-related variables may contain oscillatory modes of response. In these cases, the decay ratio for each controlled mode of response must be less than or equal to 0.25, as a result of the setpoint change testing.
FERMI 2 UFSAR 14.1-74 REV 19 10/14 A scram must not occur from low water level following a trip of one of the operating feedwater pumps. There should be a greater than 3-in. water-level margin to scram for the feedwater pump trip.
For the feedwater temperature loss test, the increase in simulated heat flux cannot exceed the predicted value referenced to the actual feedwater temperature change and power level, which will be taken from the Transient Safety Analysis Design Report.
The average rate of response of the feedwater actuator to large (>20 percent of pump flow) step disturbances shall be between 10 to 25 percent of pump rated feedwater flow per second.
This average response rate will be assessed by determining the time required to pass linearly through the 10 percent and 90 percent response points of the flow transient.
The dynamic flow response of each feedwater actuator (turbine or valve) to small (<10 percent) step disturbances shall be the following:
- a.
Maximum time to 10 percent of a step disturbance 1.1 sec
- b.
Maximum time from 10 to 90 percent of a step disturbance 1.9 sec
- c.
Peak overshoot (percentage of step disturbance) 15 percent.
14.1.4.8.22 Turbine Valve Surveillance Purpose To demonstrate acceptable procedures and maximum power levels for surveillance testing of the main turbine control and stop valves without producing a reactor scram.
Description Individual main turbine control and stop valves are tested routinely during plant operation as required for turbine surveillance testing. At several test points, the response of the reactor is observed and the maximum possible power level for performance of these tests along the 100 percent load line established.
First actuation should be between 45 and 65 percent power, and be used to extrapolate to the next test point between 70 and 95 percent power and, ultimately, to the maximum power test condition, with ample margin to scram. Note proximity to APRM flow bias scram point.
Each valve test is manually initiated and reset. The rate of valve stroking and the timing of the close-open sequence is such that the minimum practical disturbance is introduced.
If it is later decided to do bypass valve surveillance testing at power (present plans are to test these valves only when the plant is shut down), then these valves will be tested in the same manner as described above for control and stop valves.
Criteria Level 1 Not applicable.
Level 2
FERMI 2 UFSAR 14.1-75 REV 19 10/14 Peak neutron flux must be at least 7.5 percent below the scram trip setting. Peak vessel pressure must remain at least 10 lb/in.2 below the high-pressure scram setting. Peak heat flux must remain at least 5.0 percent below its scram trip point.
Peak steam flow in the high-flow lines must remain 10 percent below the high-flow isolation trip setting.
14.1.4.8.23 Main Steam Isolation Valves Purpose
- a.
To check functionally the main steam line isolation valves (MSIVs) for proper operation at selected power levels
- b.
To determine reactor transient behavior during and after simultaneous full closure of all MSIVs
- c.
To determine isolation valve closure time.
Description At selected power levels, both slow and fast single-valve closure is performed. A test of the simultaneous full closure of all MSIVs is performed at a level greater than or equal to 95 percent of rated thermal power. Should an inadvertent full closure of the MSIVs occur at a lower power level (70 percent), credit may be taken for this test if supporting analysis shows that the results can be extrapolated to the higher power condition. Correct performance of the RCIC (if L2 is reached) and relief valves is shown. Reactor process variables are monitored to determine the transient behavior of the system during and following the main steam line (MSL) isolation.
The MSIV closure times are determined from the MSL isolation data by multiplying the time increment between deenergizing the solenoids and actuation of the MSIV closed light by an extrapolation factor. The extrapolation factor will correct the time obtained to that of full closure and will be calculated for each MSIV based on previous, direct measurement data of valve full stroke length and actual position indicating switch actuation points.
The times to be determined are (a) the time from deenergizing the solenoids until the valve is 100 percent closed (tsol) and (b) the valve stroke time (ts). Time tsol equals the interval from deenergizing the solenoids until the valve reaches 90 percent closed plus 1/8 times the interval from 10 to 90 percent closure. Time ts equals the interval from when the valve starts to move until it is 100 percent closed and is based on the interval from 10 to 90 percent closure and linear valve travel from 0 to 100 percent closure.
Criteria Level 1 The MSIV stroke time (ts) shall be no faster than 3.0 sec (average of the fastest valve in each steam line) and for any individual valve 2.5 sec ts 5 sec. Total effective closure time for any individual MSIV shall be tsol plus the maximum instrumentation delay time and shall be 5.5 sec.
The positive change in vessel dome pressure occurring within 30 sec after the simultaneous full closure of all MSIVs must not exceed the Level 2 criteria by more than 25 psi. The
FERMI 2 UFSAR 14.1-76 REV 19 10/14 positive change in simulated heat flux shall not exceed the Level 2 criteria by more than 2 percent of rated value.
Flooding of the main steam lines shall not occur following the full MSIV closure test.
The reactor must scram during the full simultaneous MSIV closure test to limit the severity of the neutron flux and simulated fuel surface heat flux transient.
Level 2 During full closure of individual valves, peak vessel pressure must be at least 10 psi below scram, peak neutron flux must be at least 7.5 percent below scram, and steam flow in individual lines must be at least 10 percent below isolation trip setting. The peak heat flux must be at least 5 percent less than its trip point. The reactor shall not scram or isolate as a result of individual valve testing.
The relief valves must reclose properly (without leakage) following the pressure transient resulting from the simultaneous MSIV full closure.
The positive change in vessel dome pressure and simulated heat flux occurring within the first 30 sec after the closure of all MSIV valves must not exceed the predicted values in the Transient Safety Analysis Design Report. Predicted values will be referenced to actual test conditions of initial power level and dome pressure and will use beginning of life nuclear data. The predicted values will be corrected for the appropriate measured parameters.
After the full MSIV closure, the initial action of the RCIC and HPCI shall be automatic if L2 is reached, with RCIC capable of establishing an average pump discharge flow equal to or greater than 600 gpm within the first 50 sec after automatic initiation and HPCI capable of establishing an average pump discharge flow equal to or greater than 5000 gpm with a system response time of less than or equal to 30 sec as defined in the Technical Specifications.
If the low-low set pressure relief logic functions after the simultaneous full MSIV closure test, the open/close actions of the safety/relief valves (SRVs) shall occur within +/-20 psi of the low-low set design setpoints. The total number of opening cycles, for the SRVs opening on low-low setpoint, after initial blowdown is not to exceed four times during the initial 5 minutes following isolation. If any SRVs open as a result of this test, only one valve may reopen after the first blowdown.
Recirculation pump trip shall be initiated if L2 is reached after the MSIV full closure test.
14.1.4.8.24 Relief Valves Purpose The purposes of this test are (a) to verify that the relief valves function properly (can be opened and closed manually), (b) to verify that the relief valves reseat properly after operation, and (c) to verify that there are no major blockages in the relief valve discharge piping.
Description A functional test of each SRV shall be made as early in the startup program as practical.
This is normally the first time the plant reaches 250 psig. The test is then repeated at rated
FERMI 2 UFSAR 14.1-77 REV 19 10/14 reactor pressure. Bypass valve response is monitored during the low-pressure test, and the electrical output response is monitored during the rated pressure test. The test duration will be about 10 sec to allow turbine valves and tailpipe sensors to reach a steady state.
The tailpipe sensor response will be used to detect the opening and subsequent closure of each SRV. The bypass valve and MWe responses will be analyzed for anomalies indicating a restriction in an SRV tailpipe.
Valve capacity will be based on certification by ASME code stamp and the applicable documentation being available in the onsite records. Note that the nameplate capacity/pressure rating assumes that the flow is sonic. This will be true if the back-pressure is less than 55 percent of inlet pressure. The GE design specification requires the backpressure to be less than 40 percent of the inlet pressure, and present designs have backpressures on the order of 30 percent of the inlet pressures. The methods of calculating line losses and pressure drops are reliable enough to ensure that the 15 to 25 percent conservatism in the design more than offsets any slight inaccuracies in the calculation. A major blockage of the line would not necessarily be offset, and it should be determined that none exists through the bypass valve response signatures.
Vendor bench test data of the SRV opening responses will be available onsite for comparison with design specifications.
Criteria Level 1 There should be a positive indication of steam discharge during the manual actuation of each valve.
Level 2 Variables related to the pressure control system may contain oscillatory modes of response.
In these cases, the decay ratio for each controlled mode of response must be less than or equal to 0.25.
The temperature measured by thermocouples on the discharge side of the valves shall return to within 10°F of the temperature recorded before the valve was opened. If pressure sensors are available, they shall return to their initial state on valve closure.
During the 250 psig functional test, the steam flow through each relief valve, as measured by the initial and final bypass valve position, shall not differ by more than 10 percent from the average relief valve steam flow as measured by bypass valve position.
During the rated pressure test, the steam flow through each relief valve as measured by change in MWe is not to differ by more than 0.5 percent of rated MWe from the average of all the valve responses.
14.1.4.8.25 Turbine Stop Valve and Control Valve Fast Closure Trips Purpose To demonstrate the response of the reactor and its control systems to protective trips in the turbine and generator.
FERMI 2 UFSAR 14.1-78 REV 19 10/14 Description The turbine stop valves and the main generator breakers are tripped at selected reactor power levels. Several reactor and turbine operating parameters are monitored to evaluate the response of the bypass valves, the relief valves, and the reactor protection system (RPS). In addition, the peak values and change rates of reactor steam pressure and heat flux are determined. The ability to ride through a load rejection within bypass capacity without a scram is demonstrated.
A turbine/generator trip is performed at Test Condition 6. Should an inadvertent turbine/generator trip occur at a lower power level (70 percent), credit may be taken for this test if supporting analysis shows that the results can be extrapolated to the higher power condition. Both line circuit breakers and the generator field breaker will open, and all the turbine valves will close at the maximum rate.
Criteria Level 1 For turbine/generator trips, there should be a delay of no more than 0.1 sec following the beginning of control or stop valve closure before the beginning of bypass valve opening. The bypass valves should be opened to a point corresponding to greater than or equal to 80 percent of their capacity within 0.3 sec from the beginning of control or stop valve closure motion.
Flooding of the main steam lines shall not occur following the turbine/generator trips.
The positive change in vessel dome pressure occurring within 30 sec after either generator or turbine trip must not exceed the Level 2 criteria by more than 25 psi.
The positive change in simulated heat flux shall not exceed the Level 2 criteria by more than 2 percent of rated value.
Level 2 There shall be no MSIV closure in the first 3 minutes of the transient, and operator action shall not be required in that period to avoid the MSIV trip.
The positive change in vessel dome pressure and in simulated heat flux that occur within the first 30 sec after the initiation of either generator or turbine trip must not exceed the predicted values in the Transient Safety Analysis Design Report.
For the turbine/generator trip within the bypass valves capacity, the reactor shall not scram for initial thermal power values less than or equal to 25 percent of rated.
If the low-low set pressure relief logic functions, the open/ close actions of the SRVs shall occur within +20 psi of their design setpoints. If any SRVs open, only one valve may reopen after the first blowdown.
14.1.4.8.26 Shutdown From Outside the Control Room Purpose To demonstrate that the reactor can be brought from a normal, initial, steady-state power level to the hot shutdown condition and to verify that the plant has the potential for being
FERMI 2 UFSAR 14.1-79 REV 19 10/14 safely cooled from hot shutdown to cold shutdown conditions from outside the control room using the remote shutdown panel.
Description Hot Shutdown Demonstration:
The reactor will be shut down following a simulated main control room evacuation. The reactor will be scrammed, from outside the main control room, from a power level sufficiently high for the plant systems to be in normal operating configurations with the turbine generator in operation.
Reactor vessel water level and pressure will be controlled from a location outside the main control room. All other non-safety-related activities that would not be required during an actual remote shutdown will be performed from the main control room.
Data will be obtained at locations outside the control room to verify that the plant has achieved hot standby status and that the plant can be maintained in the stable hot standby condition.
This portion of the test will be performed with the minimum shift complement.
Cold Shutdown Demonstration:
The potential capability for cold shutdown will be demonstrated by partially cooling down the plant in the hot standby condition using controls and instrumentation located outside the control room. Cooldown can then proceed using normal procedures and operating modes from the control room to the point at which the shutdown cooling mode of residual heat removal (RHR) can be initiated. Operation of the RHR system in the shutdown cooling mode will then be initiated and controlled from outside the control room. Reactor coolant temperature will be partially reduced at a rate that will not exceed Technical Specifications limits. This demonstration will use additional personnel who can be made available to the plant before cooldown is initiated.
Approved operating procedures will be available for performance of a remote shutdown, including procedures for conducting all portions of the startup test.
Criteria Level 1 Not applicable.
Level 2 During the cold shutdown demonstration, the reactor must be brought to the point where cooldown is initiated and under control.
During the simulated control room evacuation and hot shutdown demonstration, the reactor vessel pressure and water level are controlled using equipment and controls outside the control room.
14.1.4.8.27 Flow Control Purpose
FERMI 2 UFSAR 14.1-80 REV 19 10/14
- a.
To determine the correct gain settings for the individual recirculation controllers
- b.
To demonstrate plant response to changes in circulation flow in both local manual and master manual mode
- c.
To set the limits of range of operation for the recirculation pumps.
Description The testing of the recirculation flow control system follows a "building block" approach while the plant is ascending from low to high power levels. The time responses of the individual pump flow loops and speed loops will be optimized by adjusting the gains of the controllers. By far, the most extensive testing will be performed along the mid-power load line where most of the systems' final adjustments are determined.
Criteria Level 1 The transient response of any variable related to the recirculation system to any test input must not diverge.
Level 2 The decay ratio of the speed loop response shall be <0.25 at any speed.
Flow control system limit cycles (if any) must produce a turbine steam flow variation no larger than +/-0.5 percent of the rated steam flow value.
The APRM neutron flux trip avoidance margin shall be 7.5 percent, and the heat flux trip avoidance margin shall be 5.0 percent as a result of the recirculation flow control maneuvers.
14.1.4.8.28 Recirculation System Purpose
- a.
To verify that the feedwater control system can satisfactorily control the water level without a resulting turbine trip/scram and obtain actual pump speed/flow
- b.
To verify recirculation pump startup under pressurized reactor conditions
- c.
To obtain recirculation system performance data
- d.
To verify that no recirculation system cavitation occurs in the operable region of the power flow map.
Description The reactor coolant recirculation system consists of the reactor vessel and two piping loops.
Each loop contains a centrifugal recirculation pump and two isolation valves located in the drywell and 10 jet pumps in parallel situated in the reactor downcomer. Each recirculation pump takes suction from the reactor downcomer and discharges through a manifold system to the nozzles of the 10 jet pumps. Here the flow is augmented by suction flow from the downcomer and delivered to the reactor inlet plenum.
FERMI 2 UFSAR 14.1-81 REV 19 10/14 A potential threat to plant availability is the high water level turbine trip scram caused by the level upswell that results after an unexpected trip of one recirculation pump. The change in core flow and resultant power decrease causes void formation, which the level-sensing system senses as a rise in water level. The one pump trip test is to prove that the water level will not rise enough to threaten a high-level trip of the main turbine or the feedwater pumps, while the pump restart demonstrates the adequacy of the restart procedure at the highest possible reactor power level.
Steady-state data will be collected several times during the startup test program in order to obtain a complete record of recirculation system performance.
Both the jet pumps and the recirculation pumps will cavitate at conditions of high flow and low power, where net positive suction head (NPSH) demands are high and little feedwater subcooling occurs. However, the recirculation pumps will automatically run back to minimum speed when feedwater flow decreases to 20 percent and the maximum recirculation flow is normally limited by the upper limit of the master flow controller which corresponds to the pump speed for rated flow at rated power. It will be verified that these limits are sufficient to prevent operation where recirculation pump or jet pump cavitation occurs.
Criteria Level 1 The response of any level-related variables during pump trips must not diverge.
Level 2 The simulated heat flux margin to avoid a scram shall be greater than or equal to 5.0 percent during the one pump trip recovery.
The APRM margin to avoid a scram shall be greater than or equal to 7.5 percent during the one pump trip recovery.
During the noncavitation verification, runback logic shall have settings adequate to prevent operation in areas of potential cavitation.
During the one pump trip, the reactor water level margin to avoid a high-level trip (L8) shall be greater than or equal to 3.0 in.
14.1.4.8.29 Loss of Turbine Generator and Offsite Power Purpose
- a.
To determine the reactor transient performance during the loss of the main generator and all offsite power
- b.
To demonstrate acceptable performance of the station electrical supply system.
Description The loss-of-auxiliary-power test will be performed with the generator at least l0 percent of rated electrical output. The proper response of reactor plant equipment and automatic switching equipment, as well as the proper switching of loads to the diesel generator, will be checked.
FERMI 2 UFSAR 14.1-82 REV 19 10/14 Suitable provisions are made to facilitate continuous indicating and recording capability throughout the duration of the test (variables of interest are power, core flow, vessel pressure, and reactor water level).
The transient is extended for a minimum of 30 minutes.
Criteria Level 1 The RPS, the diesel generator, RCIC, and HPCI must function properly without manual assistance. The HPCI and/or RCIC system action, if necessary, shall keep the reactor water level above the initiation level of low-pressure core spray, low pressure coolant injection (LPCI), and automatic depressurization systems.
Level 2 If the low-low set pressure relief logic functions, the open/ close actions of the SRVs shall occur within +/-20 psi of their design setpoints. If any SRVs open, only one may reopen after the first blowdown.
14.1.4.8.30 Steady-State Vibration Purpose To determine the vibration characteristics of the primary pressure boundary piping (NSSS) and engineered safety feature (ECCS) piping systems for vibrations induced by recirculation flows, hot two-phase forces, and hot hydrodynamic transients; and to demonstrate that flow-induced vibrations, similar in nature to those expected during normal and abnormal operation, will not cause damage and excessive pipe movement and vibration.
Description The systems subjected to the piping vibration testing during the startup test phase are listed in Table 3.9-1.
A complete, detailed discussion of the piping vibration and dynamic effect test program is presented in Subsection 3.9.1.1.
Criteria Acceptance criteria for this test are presented in Subsection 3.9.1.1.5.
14.1.4.8.31 Recirculation System Flow Calibration Purpose To perform a complete calibration of the installed recirculation system flow instrumentation.
Description During the testing program at operating conditions that allow the recirculation pumps to be operated at the speeds required for rated flow at rated power, the jet pump flow instrumentation is adjusted to provide correct flow indication based on the jet pump flow.
After the relationship between drive flow and core flow is established, the flow-biased APRM/RBM system will be adjusted to match this relationship.
FERMI 2 UFSAR 14.1-83 REV 19 10/14 Criteria Level 1 Not applicable.
Level 2 Jet pump flow instrumentation is adjusted so that the jet pump total flow recorder provides a correct core flow indication at rated conditions.
The APRM/RBM flow-bias instrumentation is adjusted to function properly at rated conditions.
The flow control system shall be adjusted to limit maximum core flow to 102.5 percent of rated flow by limiting motor-generator (M-G) set scoop tube position.
14.1.4.8.32 Reactor Water Cleanup System Purpose To demonstrate specific aspects of the mechanical operability of the reactor water cleanup (RWCU) system.
Description With the reactor at rated temperature and pressure, process variables are recorded during steady-state operation in three modes as defined by the system process diagram: blowdown, hot standby, and normal. A comparison of the bottom head flow indicator and the RWCU inlet flow indicator will be made.
Criteria Level 1 Not applicable.
Level 2 The temperature at the tube side outlet of the nonregenerative heat exchangers shall not exceed 130°F in the blowdown mode and shall not exceed 120°F in the normal mode.
The pump available NPSH is 13 ft or greater during the hot shutdown with loss of RPV recirculation pumps mode defined in the process diagrams.
The bottom head flow indicator will be recalibrated against the RWCU flow indicator if the deviation is greater than 25 gpm.
The cooling water supplied to the nonregenerative heat exchangers shall be less than 6 percent above the flow corresponding to the heat exchangers' capacity (as determined from the process diagram) and the existing temperature differential across the heat exchangers.
The outlet temperature shall not exceed 180°F.
14.1.4.8.33 Residual Heat Removal System Purpose
FERMI 2 UFSAR 14.1-84 REV 19 10/14 To demonstrate the ability of the RHR system to remove residual and decay heat from the nuclear system so that refueling and nuclear servicing can be performed.
Description During the first suitable reactor cooldown, the shutdown cooling mode of the RHR system will be demonstrated. The torus cooling mode will also be demonstrated, if necessary.
Criteria Level 1 Not applicable.
Level 2 The RHR system is capable of operating in the suppression pool cooling and shutdown cooling modes at the flow rates and temperature differentials indicated on the process diagrams.
14.1.4.8.34 Piping System Dynamic Response Testing Purpose To verify that piping system structural behavior under probable transient loadings is acceptable and within the limit predicted by analytical investigations.
Description The following piping systems and dynamic transient events are evaluated by test during the startup testing sequence:
- a.
Behavior of the feedwater system piping from the feedwater pump discharge to the containment penetration following a trip of a feedwater pump
- b.
Behavior of the HPCI system piping from the HPCI pump discharge to the feedwater system tee connection in the steam tunnel after a rapid start of the HPCI pump turbine
- c.
Behavior of the main steam piping from the turbine stop valve to the containment penetration after a turbine stop valve and control valve fast closure trip. This test will be conducted during an inadvertent turbine trip after the startup test program is completed
- d.
Selected main steam SRV discharge piping during SRV operation
- e.
Recirculation piping for a pump trip at 100 percent-rated flow.
The tests described above have been selected for the following reasons:
- a.
The transient phenomena identified are normal/upset transients that may be reasonably expected to occur during the life of the plant
- b.
The transients described are already planned during the system's tests to confirm system and equipment behavior in accordance with design
FERMI 2 UFSAR 14.1-85 REV 19 10/14
- c.
Evaluation of the results of these tests will aid in confirming that use of present design rules and stress analysis requirements produces system designs that are adequate for anticipated transient events.
The vibration surveys conducted during these transient events make up one portion of the piping vibration test program presented in Subsection 3.9.1.1.
Criteria Acceptance criteria for this test are presented in Subsection 3.9.1.1.5.
